TQ2-1.5V

Signal relays are a type of switching device used to control electrical circuits and are typically rated for up to 2 amps. TQ2-1.5V signal relays are a type of signal relay operating on 1.5 volts, designed to switch low power signals. They have a low on-resistance which allows them to switch signals quickly and accurately.

The working principle of the TQ2-1.5V signal relay is based on the latching principle. It works by an electromagneticscrewed-up plunger pushing and pulling the slider which makes or breaks the contacts. When the relay is at rest, the metal plunger is in the released position, with no contact made. When an external voltage is applied to the relay, it energizes the electromagnet and the plunger moves in the opposite direction, pressing against the slider and thus making the contacts. This causes the relay to switch on and off. The same principle is used in reverse when the external voltage is removed and the electromagnet de-energizes, releasing the plunger and thus breaking the contacts. This causes the relay to switch off.

The TQ2-1.5V signal relay is mainly used in low-voltage control circuits, where a switch must have a fast response time. Low-voltage relays are especially popular in circuit designs which require frequent and rapid switching in order to reduce the cost of manufacturing. They are also used in applications which require an increased flexibility and reliability with regards to switching.

In addition to being used in low-voltage circuits, theTQ2-1.5V signal relay can also be used in circuits which require extra protection from overloads. In these circuits, the relay is used as a "breaker" to prevent excessive current from causing damage. The high-voltage relays are ideal for this, as they are able to handle large currents without damage. By using a relay to switch circuits instead of a fuse, manufacturers can significantly reduce the cost of production.

The TQ2-1.5V signal relay is a highly reliable and versatile device which provides a wide range of switching applications. It is suitable for low-voltage circuits, as well as for overload protection in high-voltage circuits. It is easy to install, inexpensive and offers rapid response time.
